Version 1.0.0-alpha16
January 24, 2024
androidx.wear.compose:compose-material3:1.0.0-alpha16
is released. Version 1.0.0-alpha16 contains these commits.
New Features
- We have added
CompactButton
, which can use the same filled, filled tonal and outlined colors as Button.(I05df0)
API Changes
- We have added
RadioButton
/SplitRadioButton
as containers for selection controls, such as the Radio control. This differs from the existingToggleButton
in thatRadioButton
is selectable (and operates within a selection group) whereasToggleButton
is toggleable (and is independent). (I61275) - We are removing
LocalContentAlpha
from the Wear Compose Material3 library for consistency with the Compose Material3 library. (I49a0a) - Wear material and wear material3 components exposing a
MutableInteractionSource
in their API have been updated to now expose a nullableMutableInteractionSource
that defaults to null. There are no semantic changes here: passing null means that you do not wish to hoist theMutableInteractionSource
, and it will be created inside the component if needed. Changing to null allows for some components to never allocate aMutableInteractionSource
, and allows for other components to only lazily create an instance when they need to, which improves performance across these components. If you are not using theMutableInteractionSource
you pass to these components, it is recommended that you pass null instead. It is also recommended that you make similar changes in your own components. (Ib90fc, b/298048146) - Adds new ripple API in
wear:compose-material
andwear:compose-material3
libraries which replaces the deprecatedrememberRipple
. Also adds a temporaryCompositionLocal
,LocalUseFallbackRippleImplementation
, to revert Material components to using the deprecatedrememberRipple/RippleTheme
APIs. This will be removed in the next stable release, and is only intended to be a temporary migration aid for cases where you are providing a customRippleTheme
. See developer.android.com for migration information and more background information behind this change. (af92b21) - We have made minor improvements to the
HorizontalPageIndicator
api and its documentation. (I60efc) - We have updated
ColorScheme
to be immutable, making individual color updates less efficient, but making more common usage of colors more efficient. The reasoning behind this change is that the majority of apps wouldn't have updating individual colors as a main use case. This is still possible but it will recompose more than before, in turn we significantly decrease the amount of state subscriptions through all of material code and will impact initialization and runtime cost of more standard use cases. (Ibc2d6) - Updated
ToggleButton
andSplitToggleButton
APIs to allow disabled colors to be customized. In addition, Material Design tokens are now used for color and typography values. (If087c) - Updated Button image background colors to use Material Design tokens. (Iba215)
- We have changed the
Checkbox
,Switch
andRadioButton
components to be display-only, by removing the click handling. These components are expected to be used in(Split)ToggleButton
which handles the click, so the components are now more clearly indicated as display-only (and are not intended for standalone use on Wear). (I2322e)
Bug Fixes
- We have added tokens for motion values of durations and easings in Wear Compose Material 3. (I437cd)
- We have fixed a bug in the
ToggleButton
,SplitToggleButton
,Checkbox
,Switch
andRadioButton
so that accessibility announcements are not repeated (previously, semantic roles were duplicated). (Ica281) - We have removed the materialcore layer for
CompactButton
to improve performance. (7902858)
Version 1.0.0-alpha15
November 15, 2023
androidx.wear.compose:compose-material3:1.0.0-alpha15
is released. Version 1.0.0-alpha15 contains these commits.
API Changes
- We have renamed the Foundation level
SwipeToDismissBox
toBasicSwipeToDismissBox
. This makes the distinction clearer between the Foundation level component and the Material3 levelSwipeToDismissBox
. The latter pulls colors from theMaterialTheme
to be used in scrims and delegates the remaining implementation to theBasicSwipeToDismissBox
. (Ibecfc)
Bug Fixes
- We have removed the material-core layer for Material3 Button to improve performance. (I55555)
Version 1.0.0-alpha14
October 18, 2023
androidx.wear.compose:compose-material3:1.0.0-alpha14
is released. Version 1.0.0-alpha14 contains these commits.
API Changes
- We have removed the
indicatorStyle
parameter from the Material3HorizontalPageIndicator
- instead, it will follow the device screen shape (linear or round). (I83728) - We have separated the colors for
SplitToggleButton
from those forToggleButton
, by adding a newSplitToggleButtonColors
class. (I78bee)

Version 1.0.0-alpha01
March 22, 2023
androidx.wear.compose:compose-material3:1.0.0-alpha01
is released. Version 1.0.0-alpha01 contains these commits.
New Features
Material 3 is the next evolution of Material Design and includes updated theming and redesigned components. Material 3 on Wear Compose is designed to be cohesive with the Material 3 Compose library on Android. This first alpha release contains early, functional implementations of the following:
We will continue to develop Wear Material (
androidx.wear.compose:compose-material
) and Wear Material 3 (androidx.wear.compose:compose-material3
) in parallel. Future material3 releases will extend the widget set to include other familiar components from Compose for Wear OS, such as buttons, pickers, and sliders.The Wear Material and Wear Material 3 libraries are mutually exclusive and should not be mixed in the same app, primarily because they reference different themes which would lead to unexpected inconsistencies.

Version 1.4.0-beta01
May 14, 2024
androidx.wear.compose:compose-*:1.4.0-beta01
is released. Version 1.4.0-beta01 contains these commits.
The 1.4-beta01 release of Compose for Wear OS indicates that this release of the library is feature complete and the API is locked (except where marked as experimental). Wear Compose 1.4 includes the following new functionality:
- We have added
Modifier.rotaryScrollable
, a new modifier that connects rotary events with scrollable containers, allowing users to scroll via a crown or a rotating bezel on their Wear OS device. In addition,ScalingLazyColumn
andPicker
now support rotary input by default. Use therotaryScrollableBehavior
parameter to configure either scroll or snap behavior. For snap behavior, it is recommended to provide snap via theflingBehavior
parameter as well for touch scrolling. SwipeDismissableNavHost
now provides an entry animation for in-app transitions.PositionIndicator
is now shown by default when a screen is first displayed.SelectableChip
andSplitSelectableChip
have been added as a variation onToggleChip
- use this withRadioButton
in order to provide selectable semantics instead of toggleable semantics for accessibilityListHeader
now supports height adjustments when contents need extra height to accommodate large font sizes.
Bug Fixes
- We have fixed a bug where selectable chips announced double tap to toggle when already selected. (I7ed88)
Version 1.4.0-alpha08
May 1, 2024
androidx.wear.compose:compose-*:1.4.0-alpha08
is released. Version 1.4.0-alpha08 contains these commits.
API Changes
- We have made the following changes to the new rotary API: renamed
Modifier.rotary
toModifier.rotaryScrollable
; renamed theRotaryBehavior
interface toRotaryScrollableBehavior
and its functionhandleScrollEvent
toperformScroll
; renamedRotaryScrollableAdapter
toRotaryScrollableLayoutInfoProvider
and removed thescrollableState
property. (I0c8a6) - We have made additional changes to the rotary API: renamed
RotaryScrollableLayoutInfoProvider
toRotarySnapLayoutInfoProvider
(because this provider is only needed for rotary with snap); changed the type of thesnapOffset
parameter inRotaryScrollableDefaults.snapBehavior snapOffset
from Int to Dp. (Iddebe) - We have renamed the
clickInteractionSource
parameter onSplitSelectableChip
tocontainerInteractionSource
. (Ia8f84) - We have updated the click callback parameter names for
SplitSelectableChip
- fromonClick
toonSelectionClick
and fromonBodyClick
toonContainerClick
. (I32237)
Bug Fixes
- We have updated the horizontal padding for
PositionIndicator
to 2dp (was 5dp), in order to fix a bug where thePositionIndicator
(scroll bar) overlaps scrollable content. Please note that this change is expected to break existing screenshots that include thePositionIndicator
due to the change of padding. (I57472) - We have improved the documentation for the new rotary API by describing the differences between low-res and hi-res rotary devices. (I63abe)
- We have addressed an out-of-range exception in
SwipeDismissableNavHost
that could be triggered when interpolated alpha values were less than zero. (Ib75a1, b/335782510)

API Changes
- We have added
Modifier.rotary
, a new modifier that connects rotary events with scrollable containers, allowing users to scroll via a crown or a rotating bezel on their Wear OS device. In addition,ScalingLazyColumn
and Picker now support rotary input by default, with new overloads that include therotaryBehavior
parameter for specifying the configuration of either scroll or snap. If therotaryBehavior
parameter is set to snap, then it is recommended to provide snap via theflingBehavior
parameter as well, for touch scrolling. (I2ef6f) NestedScroll
sources Drag and Fling are being replaced byUserInput
andSideEffect
to accommodate for the extended definition of these sources that now include animations (Side Effect) and Mouse Wheel and Keyboard (UserInput). (I40579)- We have added
SelectableChip
andSplitSelectableChip
to make the distinction clearer between toggle controls such asSwitch/Checkbox
and selectable controls such asRadioButton
. This replaces the previously added overloads ofToggleChip/SplitToggleChip
withselectionControl
parameters. (Ia0217) - Updated visibility modifier of
IndeterminateStrokeWidth
inProgressIndicatorDefaults
to public. (I5b5a4)

is released. Version 1.4.0-alpha04 contains these commits.
API Changes
- We have added a new overload for
ToggleChip
andSplitToggleChip
that takes aselectionControl
parameter instead of thetoggleControl
parameter. This should be used with theRadioButton
control in order to provide selectable semantics instead of toggleable semantics for accessibility (I1d6d9) - We have updated parameter names for the new
selectionControl
overload fromonSelected
toonSelect
forToggleChip
andSplitToggleChip

wrapper has been deprecated. This API will create more invalidations of your modifier than necessary, so its use is now discouraged. Developers are encouraged to implement theinspectableProperties()
method onModifierNodeElement
if they would like to expose modifier properties to tooling. (Ib3236)
Bug Fixes
- We have fixed a documentation bug for
WearPreview*
annotations. (Id526d)
Version 1.4.0-alpha02
February 7, 2024
androidx.wear.compose:compose-*:1.4.0-alpha02
is released. Version 1.4.0-alpha02 contains these commits.
Bug Fixes
- We have fixed a bug in swipe-to-reveal, where it was possible to interact with (and cancel) a committed action on one item by starting to swipe another item.(Ide059)
- We have updated the
ListHeader
to support height adjustments when contents need extra height to accommodate large font sizes. (I7290c, b/251166127)
Version 1.4.0-alpha01
January 24, 2024
androidx.wear.compose:compose-*:1.4.0-alpha01
is released. Version 1.4.0-alpha01 contains these commits.
New Features
- We have added entry animation to
SwipeDismissableNavHost
for in-app transitions.(cfeb79a) PositionIndicator
is now shown by default when a screen is first displayed. This change was introduced in order to help meet Wear Quality guidelines. Unfortunately, it means that screenshot tests will need to be updated on screens that includePositionIndicator
, as thePositionIndicator
would not previously have been displayed. (419cef7)
API Changes
- We have added a new ripple API in
wear:compose-material
andwear:compose-material3
libraries which replaces the deprecatedrememberRipple
. Also adds a temporaryCompositionLocal
,LocalUseFallbackRippleImplementation
, to revert Material components to using the deprecatedrememberRipple/RippleTheme
APIs. This will be removed in the next stable release, and is only intended to be a temporary migration aid for cases where you are providing a customRippleTheme
. See developer.android.com for migration information and more background information behind this change. (af92b21) - We have updated
ColorScheme
to be immutable, making individual color updates less efficient, but making more common usage of colors more efficient. The reasoning behind this change is that the majority of apps wouldn't have updating individual colors as a main use case. This is still possible but it will recompose more than before, in turn we significantly decrease the amount of state subscriptions through all of the material code and will impact initialization and runtime cost of more standard use cases. (f5c48b7) - Wear material and Wear material3 components exposing a
MutableInteractionSource
in their API have been updated to now expose a nullableMutableInteractionSource
that defaults to null. There are no semantic changes here: passing null means that you do not wish to hoist theMutableInteractionSource
, and it will be created inside the component if needed. Changing to null allows for some components to never allocate aMutableInteractionSource
, and allows for other components to only lazily create an instance when they need to, which improves performance across these components. If you are not using theMutableInteractionSource
you pass to these components, it is recommended that you pass null instead. It is also recommended that you make similar changes in your own components. (f8fa920) - We have updated
rememberExpandableState
to save expandable state. This ensures that data is stored when navigating to another screen and restored when coming back to the original screen. (5c80095)
Bug Fixes
- We have updated the
ReduceMotion
setting to use a lifecycle aware listener. (7c6b122) - We have updated
TouchExplorationStateProvider
’s Listener to be lifecycle aware (be28b01) - We have removed the materialcore layer for
CompactButton
to improve performance (25db8e9) - We have made
BasicSwipeToDismissBox
more robust to NaN offsets to avoid exceptions (b983739) - We have updated
BasicSwipeToDismissBox
to ensure alpha values are within the range 0,1 - We have fixed a bug in the
ToggleButton
,SplitToggleButton
,Checkbox
,Switch
andRadioButton
so that accessibility announcements are not repeated (previously, semantic roles were duplicated) (d11eeb7)
Version 1.3
Version 1.3.1
April 3, 2024
androidx.wear.compose:compose-*:1.3.1
is released. Version 1.3.1 contains these commits.
Bug Fixes
- We have fixed a bug in swipe-to-reveal, where it was possible to interact with (and cancel) a committed action on one item by starting to swipe another item. (Ide059)
Version 1.3.0
January 24, 2024
androidx.wear.compose:compose-*:1.3.0
is released. Version 1.3.0 contains these commits.
Important changes since 1.2.0
- The
SwipeToDismissBoxState
class,SwipeToDismissValue
enumeration, andModifier.edgeSwipeToDismiss
extension function are now each part of theandroidx.wear.compose.foundation
package, instead of theandroidx.wear.compose.material
package. This updated architecture allows you to implement gesture handling independently from other design considerations. Material Design workflows, such as applying colors from a configured theme, are handled separately. - The
SwipeToRevealCard
andSwipeToRevealChip
classes help you implement therecommended swipe-to-reveal guidance
. TheSwipeToRevealSample
class demonstrates how to use these components. Our 1.3.0-alpha02 release introduced a change that causes
Chip
andToggleChip
objects to grow in height to better support user-selected font scaling. This can cause some clipping to occur. To fix this issue, thelarge
shape forMaterialTheme
now uses a larger corner radius (26 dp instead of 24 dp).Chip
andToggleChip
objects use this new corner radius to avoid clipping content on the corners of Chip andToggleChip
.- Most
Chips
andToggleChips
are unchanged, given their default 52 dp height. However,Chip
andToggleChip
objects that contain multiple lines of primary or secondary label text, or for which the height has been overridden, could cause screenshot tests to break.
- Most
Additional changes
For a more complete set of the changes introduced in version 1.3.0, see the beta01 release notes.
Recommendations for implementation
- If your app allows users to pan around the screen's content, such as in a map-based app, turn off swipe handling by setting
userSwipeEnabled
tofalse
in theSwipeDismissableNavHost
composable, and include a button that allows users to go to the previous screen. - To turn off animations for a position indicator during fade-in and position-change animations within a scrolling list, use a
SnapSpec
object. - While waiting for a media app to load content for playback, show a blank
Placeholder
composable. - To create a collection of expandable items on demand, consider using the experimental
ExpandableStateMapping
class.
Version 1.3.0-rc01
January 10, 2024
androidx.wear.compose:compose-*:1.3.0-rc01
is released. Version 1.3.0-rc01 contains these commits.
Bug Fixes
-
We have updated the
MaterialTheme
large shape to use a 26dp rounded corner radius and this will now be used by Chip andToggleChip
. This change is needed to support height adjustments when contents need extra height to accommodate large font sizes—otherwise, the existing stadium shape clips some text content.Figure 1: Text clipped on corners. Figure 2: Text not clipped. This change may cause a breakage in screenshot tests. (I2e6ae)
Version 1.3.0-beta02
December 13, 2023
androidx.wear.compose:compose-*:1.3.0-beta02
is released. Version 1.3.0-beta02 contains these commits.
Bug Fixes
- We have restored the intended swipe motion in
BasicSwipeToDismissBox
. This had been altered in a previous release, such that the slide part of the transition occurred while the finger was touching the screen. (Id8e76)
Version 1.3.0-beta01
November 15, 2023
androidx.wear.compose:compose-*:1.3.0-beta01
is released. Version 1.3.0-beta01 contains these commits.
The 1.3-beta01 release of Compose for Wear OS indicates that this release of the library is feature complete and the API is locked (except where marked as experimental). Wear Compose 1.3 includes the following new functionality:
SwipeToDismissBoxState
,SwipeToDismissValue
andModifier.edgeSwipeToDismiss
have been migrated fromandroidx.wear.compose.material
toandroidx.wear.compose.foundation
, along with the underlying swipe-to-dismiss implementation inBasicSwipeToDismissBox
. This allows the gesture handling for swipe-to-dismiss to be used independently of Material Design, for example from theSwipeDismissableNavHost
inandroidx.wear.compose.navigation
.SwipeToDismissBox
fromandroidx.wear.compose.material
is still recommended to be used with Material Design, because it pulls colors from theMaterialTheme
, then delegates the remaining implementation to theBasicSwipeToDismissBox
.SwipeDismissableNavHost
now supports a newuserSwipeEnabled
parameter so that swipe handling can be turned off for screens where it is not required.BasicSwipeToDismissBox
has improved focus handling usingHierarchicalFocusCoordinator
.SwipeToReveal
has newSwipeToRevealCard
andSwipeToRevealChip
composables in Material that follow the recommended UX guidance forCard
andChip
. It also has undo support for the secondary action.DefaultTextStyle
now turns off font padding to be consistent across the Android Platform.Chip
andToggleChip
now adjust their height to accommodate content that has grown due to large fonts for accessibilityPositionIndicator
now has individual animation specs for the fade-in, fade-out and position-change animations. For performance reasons, we recommend that fade-in and position-change are turned off when used with scrollable lists.ExpandableStateMapping
provides a new way to generateExpandableStates
when they need to be created on demand and not necessarily with a@Composable
scope.Placeholder
now allows resetting if the content is no longer in the ready state. Also, the reduce motion setting now applies to the shimmering effect and wipe-off motion onPlaceholder
.
Known Issues
PositionIndicator
is not initially shown when a screen is first displayed. We intend to make a change in an early 1.4 alpha so that it will be initially shown, but without any animation.
API Changes
- We have renamed the Foundation level
SwipeToDismissBox
toBasicSwipeToDismissBox
. This makes the distinction clearer between the Foundation level component and the Material levelSwipeToDismissBox
. The latter pulls colors from theMaterialTheme
to be used in scrims and delegates the remaining implementation to theBasicSwipeToDismissBox
. (Ibecfc) - We have marked
rememberExpandableStateMapping
as experimental and improved the performance ofexpandableItem
. (I5f6bc) - We have replaced the
SwipeToRevealAction
class in the MaterialSwipeToReveal
Card and Chip APIs with a slot-based API usingSwipeToRevealPrimaryAction
,SwipeToRevealSecondaryAction
andSwipeToRevealUndoAction
composables. Please see sample code for examples on how to use the new API. (Ia8943) - We have replaced the
PositionIndicator
animation flags withAnimationSpec
parameters. The individual animations can be disabled by passingsnap
as theAnimationSpec
. (I6c523)
Bug Fixes
- We have fixed a bug triggered by limited curved text when size is limited (I50efe)
- We have addressed a potential NaN crash related to
curvedComposable
(I970eb) - We have reverted the removal of the position change highlight animation on
PositionIndicator
. (Ieb424) - We have removed the material-core layer for material Chip to improve its performance. (If2dcb)
Version 1.3.0-alpha08
October 18, 2023
androidx.wear.compose:compose-*:1.3.0-alpha08
is released. Version 1.3.0-alpha08 contains these commits.
API Changes
- We have added individual flags to
PositionIndicator
overloads, to control different animations:showFadeInAnimation
,showFadeOutAnimation
andshowPositionAnimation
. The previous API has been deprecated and forwards calls to the new one. For performance reasons and for UX consistency, when thePositionIndicator
is used with a scrollable list, we recommend switching offshowFadeInAnimation
andshowPositionAnimation
flags. IfPositionIndicator
is used as a standalone indicator, for example for volume change, then we recommend having all 3 animations turned on. (I44294) - We have deprecated the Material
SwipeToDismissBoxState
,SwipeToDismissValue
andedgeSwipeToDismiss
following the migration of Swipe-to-Dismiss functionality towear.compose.foundation
. Please replace with thewear.compose.foundation
equivalents. (Iee8c9)
Bug Fixes
- We have updated the baseline profiles for wear compose foundation, material and navigation libraries. (Idb060)
- We have reverted a behavioral change for
PositionIndicator
introduced in a previous CL, such that thePositionIndicator
was animated when a screen was initially displayed. We intend to make a similar change in an early 1.4 alpha, so that thePositionIndicator
is initially displayed, but without any animation. (I41843) - We have addressed some performance issues in
PositionIndicator
. (I1c654, b/302399827) - We have optimized performance of the touch exploration state provider default implementation to rely on
State<Boolean>
rather than derived state. (Ieec4d) - We have set
systemGestureExclusion
rectangles for Android 13 and higher. (Ib1f4b)
Version 1.3.0-alpha07
October 4, 2023
androidx.wear.compose:compose-*:1.3.0-alpha07
is released. Version 1.3.0-alpha07 contains these commits.
API Changes
- We have added individual flags to
PositionIndicator
to control different animations:showFadeInAnimation
,showFadeOutAnimation
andshowPositionAnimation
. The previous API has been deprecated and forwards calls to the new one. For performance reasons and for UX consistency, when thePositionIndicator
is used with a scrollable list, we recommend switching offshowFadeInAnimation
andshowPositionAnimation
flags. IfPositionIndicator
is used as a standalone indicator, for example for volume change, then we recommend having all 3 animations turned on. (Ia2d63)
Bug Fixes
- We have made improvements to the swipe to reveal motion by adding a fade animation to the primary action text, and fading the secondary action/changing the icon scale on full swipe expansion. (Ib7223)
- It is recommended that Swipe to Reveal actions are made accessible and we have added custom accessibility actions to our Swipe to Reveal samples. (I42224)
- We have improved the performance of
SwipeToDismissBox
, including refactoring to ensure that the initial logic does not trigger a recomposition. TheSwipeToDismissBox
is now drawn as the full screen size. (Ie0aa2) - We have fixed a bug when the
PositionIndicator
incorrectly disappeared. (I2091a) - Improved performance of
PositionIndicator
by optimizing recompositions. New flags to control the animations (fadeIn
,fadeOut
andpositionChange
) have been added subsequently (see API Changes) (Ifac7d) - We have added Microbenchmark tests for
PositionIndicator
(Idf875)

is released. Version 1.3.0-alpha03 contains these commits.
API Changes
- We have added two new composables in Material for implementing
SwipeToReveal
with Cards and Chips. These composables follow the recommended UX guidance on the component and make it easier for developers to implementSwipeToReveal
with the existing components in Wear Material. (I7ec65) - We have turned on the
FloatRange
annotations as API constraints, which were previously stated in comments. (Icb401)
Bug Fixes
- We have moved the initial scrolling logic of
ScalingLazyColumn
insideonGloballyPositioned()
. (Ic90f1) - We are now using

is released. Version 1.3.0-alpha02 contains these commits.
API Changes
- We have provided
ExpandableStateMapping
, a new way to generateExpandableStates
, for cases in which they need to be created on demand, not necessarily within a@Composable
scope (Iff9e0) SwipeToDismissBox
has been migrated fromandroidx.wear.compose.material
toandroidx.wear.compose.foundation
package. (I275fb)- Updated API files to annotate compatibility suppression. (I8e87a, b/287516207)

public. (Ieeaf7) - Added functionality to turn off swipe handling in
SwipeDismissableNavHost
via the newuserSwipeEnabled
parameter. (Id2a0b, b/230865655) - We have updated the Wear Compose Navigation library to use the new
SwipeToDismissBox
from Wear Compose Foundation. (I4ff8e)
Bug Fixes
- We have fixed a z-order bug where
expandedItem
did not show the correct content after clicking a button's behavior when they have buttons. (I1899d, b/289991514) - Improve focus handling of
SwipeToDismissBox
(and henceSwipeDismissableNavHost
) using theHierarchicalFocusCoordinator
(I45362, b/277852486) - We have made a fix to the gesture handling in
SwipeableV2
. (I89737) - We have finalized the baseline profiles for our 1.2 release. (Id5740)
- Following the migration of
SwipeToDismissBox
to Foundation, the MaterialSwipeToDismissBox
implementation now forwards to Foundation and supplies default color values from its theme.(If8451) - We have added heading semantics to
ListHeader
. (Ic5420) Chip
andToggleChip
will now adjust their height to accommodate content that has grown due to large fonts for accessibility, when required. (Iaf302)- Fixed a bug in the semantic role of
SplitToggleChip
’s tappable area, for accessibility. (Ieed3a) - The reduce motion setting now turns off the shimmering effect and wipe-off motion on placeholders. (I91046)
Stepper
andInlineSlider
now support repeated clicks on long press so that you can quickly increase/decrease value ofStepper
andInlineSlider
by holding the + or - buttons. (I27359)
Version 1.3.0-alpha01
June 21, 2023
androidx.wear.compose:compose-*:1.3.0-alpha01
is released. Version 1.3.0-alpha01 contains these commits.
Bug Fixes
- As announced in
1.2.0-alpha07
and1.2.0-alpha10
, we are now changing theDefaultTextStyle
to turn off font padding to be consistent across the Android Platform. This will address some cases of text clipping with large font sizes and may also impact screen layouts, so that screenshot tests need to be updated. For example, we see text clipping here (Ic6a86)
![Text clipped with large font size](/https/developer.android.com/static/jetpack/androidx/images/IncludeFontPadding-True.png)
- It is no longer present when font padding is turned off:
![Text not clipped with large font size](/https/developer.android.com/static/jetpack/androidx/images/IncludeFontPadding-False.png)
- We have updated
wear.compose.foundation
to be an API dependency ofwear.compose.material
(I72004, b/285404743) - We have fixed a bug in
SwipeToDismissBox
. Background and content keys are now passed to the remember block so that new modifiers are created when the content or background changes. (Ib876c, b/280392104) - We have updated
TimeText
to use the locale when choosing the format for 12 or 24 hour time. (If4a3d) - We have fixed an inconsistency in
SwipeToDismissBox
contentScrimColor
default parameters. (I2d70f) - We have improved the motion handling in
SwipeToReveal
. (I28fb7)
Known Issues
- Supporting user-configured font sizes is an accessibility requirement. We know that multiline Chips can lead to text-clipping when displayed with large font sizes, so we will be updating Chip in an early 1.3 alpha version to make height adjustments in those cases.

What’s in Compose for Wear OS 1.2
The 1.2-beta01 release of Compose for Wear OS indicates that this release of the library is feature complete and the API is locked (except where marked as experimental). Wear Compose 1.2 includes the following new functionality:
expandableItem
andexpandableItems
are two newFoundation
components that support expanding items within aScalingLazyColumn
. UseexpandableItem
for a single expandable item, such as Text in which the number of lines. UseexpandableItems
for a group of expandable items andexpandableButton
to simplify creating a button that collapses after the content is expanded.HierarchicalFocusCoordinator
- this experimental composable enables marking sub-trees of the composition as focus enabled or focus disabled.Picker
- the API now includesuserScrollEnabled
to control whether the picker is active for user scrolling.PickerGroup
- a new composable for handling multiple pickers together. It handles focus between the pickers using theHierarchicalFocusCoordinator
API and enables auto-centering of picker items.Placeholder
- we have made updates to the shimmer and ‘Wipe Off’ animations. The wipe-off effect is now immediately applied when the content is ready.ScalingLazyColumn
- we have migratedScalingLazyColumn
and associated classes fromandroidx.wear.compose.material.ScalingLazyColumn
toandroidx.wear.compose.foundation.lazy.ScalingLazyColumn
. Please update to use theFoundation.Lazy
version.SwipeToReveal
- we have added experimental support for swipe-to-reveal as a means to access secondary actions, supplementing the existing ‘long press’ pattern.Stepper
- now has an overload with an additionalenableRangeSemantics
parameter to facilitate disabling the default range semantics.Previews
- we have added the following custom annotations for previewing composables on Wear screens:WearPreviewSmallRound
previews the composable on a small, round device;WearPreviewLargeRound
previews the composable on a large round device;WearPreviewSquare
previews the composable on a square device. Also, the following and multi-preview annotations:WearPreviewFontScales
previews the composables on a wear device with multiple font sizes, whileWearPreviewDevices
previews the composables on different wear devices.- We have added a
DefaultTextStyle
to Wear Compose which defaults thePlatformTextStyle.includeFontPadding
property to true (this is the current setting). This will allow us to synchronize turning off font padding by default with the Compose libraries in an early 1.3 alpha version - see 1.2.0-alpha10 for more information.
New Features
- We have added experimental support for disabled scaling and fading animation when reduce_motion setting is switched on. (I58024)
Bug Fixes
- Improved documentation for
angularWidthDp
inCurvedSize.kt
(Iab75c) SwipeDismissableNavHost
now logs a warning with potential causes of empty backstack. This is done to prevent unexpected crashes caused because ofIllegalArgumentException
which was thrown when the backstack was empty. (I04a81, b/277700155)
Version 1.2.0-alpha10
May 10, 2023
androidx.wear.compose:compose-*:1.2.0-alpha10
is released. Version 1.2.0-alpha10 contains these commits.
New Features
- We have added support for Swipe to Reveal, as a means to access secondary actions. This pattern supplements the ‘long press’ pattern, the existing way a user could reveal (different) secondary actions. (I60862)
API Changes
- We have added
RevealScope
to action composables inSwipeToReveal
, which gives access to the offset at which additional actions are revealed. (I3fd56)
Bug Fixes
- Fixed an issue with
ScalingLazyColumn
being stuck on Wear API 33 after fling (Ic4599) - We have made some performance improvements to
PositionIndicator
for jank reduction. (I35e92) - We have fixed a bug in Chip and
CompactChip
where the semantic role was no longer being set toRole.Button
. (I93f91, b/277326264)
Known Issues
We have identified a bug in Android Studio which causes failure in rendering preview when annotated with @WearPreviewDevices and @WearPreviewFontScales - a fix is planned for release soon. Please note that the other wear preview annotations work as intended in Android Studio Giraffe 2022.3.1 and beyond.
In version 1.2.0-alpha07 we added DefaultTextStyle to Wear Compose, maintaining the existing PlatformTextStyle.includeFontPadding value as true - for background, see Fix font padding in Compose. We will be changing the DefaultTextStyle to turn off font padding in an early 1.3 alpha version, to be consistent across the Android Platform. This will address some cases of text clipping with large font sizes and may also impact screen layouts, so that screenshot tests need updating. For example, with large font sizes we see text clipping here:
![Text clipped with large font size](/https/developer.android.com/static/jetpack/androidx/images/IncludeFontPadding-True.png)
- It is no longer present when font padding is turned off:
![Text not clipped with large font size](/https/developer.android.com/static/jetpack/androidx/images/IncludeFontPadding-False.png)
The new setting can be adopted now by overriding the typography in your theme - see example code.

- We have moved the Expandable Item components (added in 1.2.0-alpha06) from material to foundation, since they had no meaningful reference to the
MaterialTheme
. (Ib0525)
Bug Fixes
- We have fixed a crash that occurred in a screen using
PickerGroup
, by ensuring thatPickerGroup
handles focus correctly when no Picker has the focus. Also added support for RSB scrolling in our Picker demos. (If8c19) - We have improved the dialog transitions - the intro transition is now smoother to match the outro transition. (Ib5af9)
- We have added a
DefaultTextStyle
to Wear Compose which defaults thePlatformTextStyle.includeFontPadding
property to true (this is the current setting). This will allows us to synchronize turning off font padding by default with the Compose libraries in the future - see (Fix font padding in Compose) for background. (I2aee8) - Reverted an
UpsideDownCake
preview dependency via activity-compose that blocked publishing apps to the Google Play Store. (I6443d)
Version 1.2.0-alpha06
March 8, 2023
androidx.wear.compose:compose-*:1.2.0-alpha06
is released. Version 1.2.0-alpha06 contains these commits.
API Changes
- Add
CurvedBox
component, which places components on top of each other in the curved world. (I29200) - Added Expandable Item(s) - two new components to support either a group of expandable items in a
ScalingLazyColumn
, or an expandable single item, such as Text in which the number of lines expands. (I95dd5) - We have added the following custom annotations for previewing composables on Wear screens:
WearPreviewSmallRound
previews the composable on a small, round device;WearPreviewLargeRound
previews the composable on a large round device;WearPreviewSquare
previews the composable on a square device. Also, the following and multi-preview annotations:WearPreviewFontScales
previews the composables on a wear device with multiple font sizes, whileWearPreviewDevices
previews the composables on different wear devices. To use these previews, you must be using the latest Android Studio (Giraffe Canary 6) or beyond. Please note that if these annotations do not suit your purpose, Preview can still be used and supports further customisations via parameters. (I397ff) - We have marked
HierarchicalFocusCoordinator
as experimental while it is considered as a candidate to be moved into core compose libraries, given its wide applicability. (I3a768)
Bug Fixes
- Fixed a bug on
HierarchicalFocusCoordinator
, when the lambda passed in for thefocusEnabled
parameter is changed, we now correctly use the new one. (Icb353) - We have updated the default disabled content color to Background when using primary colors as the background in
Button
,CompactButton
,Chip
,CompactChip
andToggleButton
. This improves the contrast for accessibility. (I527cc)
Version 1.2.0-alpha05
February 22, 2023
androidx.wear.compose:compose-*:1.2.0-alpha05
is released. Version 1.2.0-alpha05 contains these commits.
API Changes
- Updated
PickerGroup
API to allow propagating the min constraints to the composable optionally. When set as true, the minimum constraints passed from the parent composable will be allowed on thePickerGroup
. If set as false,PickerGroup
will reset the minimum constraints. (I3e046) - We have added
animateScrollToOption
to the Picker API in order to support programmatic animation to a specific Picker option (I6fe67)
Bug Fixes
- We have updated
HorizontalPageIndicator
to support right-to-left layouts. (Ia4359) - Added Screenshot tests for right-to-left layout in
HorizontalPageIndicator
(I6fbb8) - Added further tests to
SwipeDismissableNavHostTest
that useTestNavHostController
(I61d54)
Version 1.2.0-alpha04
February 8, 2023
androidx.wear.compose:compose-*:1.2.0-alpha04
is released. Version 1.2.0-alpha04 contains these commits.
New Features
PickerGroup
for handling multiple pickers together using the focus API. It handles the focus between the different pickers, enables auto-centering of the pickers based on parameters and allows developers to change the focus between different pickers while handling the events from the group. In talkback mode, thePickerGroup
handles the talkback focus by moving the focus to the selected Picker from the group. (I60840)
API Changes
- We have added an overload to Stepper with an additional
enableRangeSemantics
parameter in order to facilitate disabling the default range semantics (Ia61d4)
Bug Fixes
- Allow
ScalingLazyColumn
to be nested within a horizontally scrolling page (Iec3f8, b/266555016) - Improvement of Stepper kdocs and
StepperTest
tests clean-up. (Ic118e) - Updated
androidx.navigation
dependency to version 2.5.3 (If58ed)
Version 1.2.0-alpha03
January 25, 2023
androidx.wear.compose:compose-*:1.2.0-alpha03
is released. Version 1.2.0-alpha03 contains these commits.
API Changes
- We have migrated
ScalingLazyColumn
(and associated classes) fromandroidx.wear.compose.material.ScalingLazyColumn
toandrdoidx.wear.compose.foundation.lazy.ScalingLazyColumn
(see this example for migration). This new location more closely matches that ofcompose.foundation.lazy.LazyColumn
and is more natural as it is not an opinionated Material component. The change is happening now in preparation for a new Material3 library, which we will be working on in parallel with the existing Material library. (I060e7)
The following changes are part of the ScalingLazyColumn
migration from Material to Foundation.Lazy
:
PositionIndicator
apis targeting MaterialScalingLazyColumn
have been deprecated - please update toFoundation.Lazy ScalingLazyColumn
. AdditionallyanchorType
field was added toScalingLazyListLayoutInfo
. (I29d95)ScalingLazyColumn
has been marked as deprecated in the Wear Compose Material package (I16d34)- We have updated the
ScrollAway
modifier to useScalingLazyListState
from Wear ComposeFoundation.Lazy
and deprecated the overload that tookScalingLazyListState
from Wear Compose Material. (Ifc42c) - We have updated the Dialog APIs to use
ScalingLazyListState
fromFoundation.Lazy
and deprecated the overloads that used MaterialScalingLazyListState
(Ic8960) - We have updated the Picker APIs to use
ScalingParams
fromFoundation.Lazy
and deprecated the overloads that used MaterialScalingParams
. (Idc3d8)
Bug Fixes
- We have fixed a bug that caused unnecessary recompositions in
ScalingLazyListState.centerItemIndex
by ensuring that it only pushes updates when the value actually changes (Ia9f38) - We have improved the performance of
SwipeToDismissBox
(I3933b) - Added benchmark tests for
ScalingLazyColumn
in Wear Compose Foundation (Ie00f9) - We have updated some internal
ScalingLazyColumn
classes methods in Material to use their equivalents fromFoundation.Lazy
(I38aab) - We have fixed some issues in Picker tests and add more tests for checking scroll with offset (I6ac34)
- We migrated the
ScalingLazyColumn
Integration Demos to depend onFoundation.Lazy
instead of MaterialScalingLazyColumn
(Ic6caa) - We have added optional
fromDate/toDate
parameters to ourDatePicker
demo (I961cd)
Version 1.2.0-alpha02
January 11, 2023
androidx.wear.compose:compose-*:1.2.0-alpha02
is released. Version 1.2.0-alpha02 contains these commits.
API Changes
- Android Compose UI tests will now run layout passes for each frame when executing frames to get to idle (e.g. via
waitForIdle
). This may affect tests that assert on individual frames of layout animations. (I8ea08, b/222093277) - The parameter
minLines
is added to Wear Text for consistent behaviour withBasicText
(I24874) CompactChipTapTargetPadding
has been made public so that it appears in the documentation (If1e70, b/234119038)
Bug Fixes
- Disable multiplatform builds for
wear.compose
packages (Iad3d7) - Fix kdocs for
scrollToOption
(I6f9a0) PlaceholderState.rememberPlaceholderState()
updated to userememberUpdatedState
to that the state will update if theonContentReady
lambda. (I02635, b/260343754)- We have fixed a text jittering issue seen in the
Picker
component by leveraging the new compositing strategy added toModifier.graphicsLayer
. (I99302) - We have fixed a bug that caused flickering in our
DatePicker
demo (I660bd) - We have improved the accessibility for the 12-hour time and date picker demos (I05e12)
- We have updated our time and date picker demos so that the pickers are not affected by RSB changes when unselected (I4aecb)
Version 1.2.0-alpha01
December 7, 2022
androidx.wear.compose:compose-*:1.2.0-alpha01
is released. Version 1.2.0-alpha01 contains these commits.
New Features
- We’ve updated the experimental Placeholder functionality so that the “Wipe Off” effect is immediately applied when the content is ready rather than waiting for the next animation loop to start. We have also made some updates to the shimmer and wipe off animations. (I5a7f4)
API Changes
- We have added a
HierarchicalFocusCoordinator
composable to enable marking sub-trees of the composition as focus enabled or focus disabled.(I827cb) - We have added a new property to override the semantic role for
ToggleButton
.(I67132) - We have updated
TimeTextDefaults.TimeFormat12Hours
to remove AM/PM inTimeText
. This will change the default value oftimeSource
parameters inTimeText
API. (I1eb7f) - We have extended the Picker API to improve accessibility for screens with multi-picker. There is a new property
userScrollEnabled
to control whether the picker is active for user scrolling. (I3c3aa)
Bug Fixes
- We have changed the default border width for an
OutlinedButton/OutlinedCompactButton
from 2.dp to 1.dp to match final UX specs. (Icf84d) - In order to reduce the effect of the first item added to an empty
ScalingLazyColumn
appearing to scroll into place we have added an estimatedautoCentering topPadding
when the contents are empty. This change calculates the amount of top padding needed by assuming an initial item of height 0.dp. ForScalingLazyListAnchorType.ItemStart
this will calculate the correct top padding, forScalingLazyListAnchorType.ItemCenter
this calculation will be incorrect as the height of the items is needed to correctly size the contents resulting in a small scroll into place effect based on the items real height.(I239a4) - We have updated the background scrim applied to the
SwipeToDismiss
animation to match the Wear platform. (I9003e) - We have fixed
PositionIndicator
handling ofLazyListState
andScalingLazyListState
for list items of size 0 to avoid divide by zero errors.(Ic28dd)

, and androidx.wear.compose:compose-navigation:1.1.0-rc01
are released. Version 1.1.0-rc01 contains these commits.
Bug Fixes
- We have added baseline profile rules for
Placeholders
,ScrollAway
,RadioButton
,Switch
,Checkbox
,OutlinedButton
,OutlinedCompactButton
,OutlinedChip
andOutlinedCompactChip
. (I8249c) - We have fixed a bug in
Modifier.scrollAway
so that if the specifieditemIndex
is invalid (for example, if that item index is out of range), then theTimeText
will now still be displayed. (I2137a) - We have updated the
SwipeToDismissBox
animation to match the platform implementation. After the initial squeeze animation, the screen now slides off to the right once the dismissal has been triggered. (I41d34) - As an optimization, we have updated
Modifier.scrollAway
to only read thescrollState
inside the measure block to avoid recomposing the modifier after each remeasure. (I4c6f1) - We have added documentation and a sample to placeholders to show the correct ordering for
Modifier.placeholder
andModifier.placeholderShimmer
when applied to the same composable. (Ie96f4, b/256583229) - We have changed the default border width for an
OutlinedCompactChip/OutlinedChip
from 2.dp to 1.dp to match final UX specs. (Ib3d8e) - We have fixed a bug in
rememberPickerState
where updated inputs were not saved, so that composables were not updated after changes to the inputs. (I49ff6, b/255323197) - We have made some UI updates to the placeholders, 1) change the shimmer gradient to 1.5x the screen size, 2) add easing (cubic bezier) of the shimmer progression and 3) speed up the wipe-off animation (250ms). (Id29c1)
- We have corrected a UI bug in the placeholder wipeOff effect where Chip and Card backgrounds were wiping off slightly early due to not taking the component’s position on screen into account. (I2c7cb)
- We have updated the placeholder background drawing to merge colors rather than layer them where possible to reduce the risk of alpha blending of the different cropped layers from allowing underlying colors to bleed through at the placeholder background edges. (I2ea26)
- We have corrected the calculation of
ScalingLazyListState.centerItemIndex/centerItemOffset
so that if two items sit either side of the viewport center line the one that is closest will be considered as thecenterItem
. (I30709, b/254257769) - We have corrected a bug in the
ScalingLazyListState.layoutInfo.visibleItemsInfo
which was reporting incorrect offsets duringScalingLazyColumn
initialization. Now an empty list will be returned until all list items are visible and have the correct offsets. Check forScalingLazyListState.layoutInfo.visibleItemsInfo.isNotEmpty()
will confirm that theScalingLazyColumn
initialization is complete and items are visible. (I3a3b8)

What’s in Compose for Wear OS 1.1
The 1.1.0-beta01 of Compose for Wear OS indicated that this release of the library is feature complete and the API locked.
- Wear Compose 1.1 release includes the following new functionality:
- Picker - Accessibility improvements to Picker so that multi-picker screens are navigable with screen readers and the content description is accessible
- Picker
contentDescription
parameter is now used only for the selected Picker option and takes a nullable String (in the previous commit, it was necessary to pass a mapping from option to the content description, but only the selected option was used). - Picker items are now always center-aligned, fixing a bug when setting
gradientRatio
to zero had the side-effect of changing the alignment. Chip/ToggleChip
- We have updated the default gradients forChip/ToggleChip
to bring them in line with the latest UX spec.ChipDefaults.gradientBackgroundChipColors
has been updated to start from 50% of primary rather than 32.5%.Chip/ToggleChip
- Added overloads for modifying Chip shapesChip/Button/ToggleButton
- Added a new outlined style for Chips and Buttons and newOutlinedChip
andOutlinedButton
composables that provide a transparentChip/Button
with a thin border.- Card - Updated the default gradients for Cards to bring them in line with the latest UX spec.
CardDefaults.cardBackgroundPainter
has been updated to start from 30% of primary and end at 20% ofonSurfaceVariant
(was previously 20% to 10%onSurfaceVariant
).ToggleChip.toggleChipColors
changes from a linear gradient of 75% surface to 32.5% primary to 0% surface to 50% primary. Button/ToggleButton
- Added properties for modifying button shapes.- Theme - Updated a number of the default colors in the
MaterialTheme
in order to improve accessibility as the original colors did not have sufficient contrast resulting in difficulties for users to differentiate chip/card/button backgrounds from the theme background color. InlineSlider/Stepper
- Button roles added so thatTalkback
can recognise them as buttons.- Scaffold -
PositionIndicator
now is positioned and sized so that it only takes the space needed. This is useful, for example, if semantic information is added to it, talkback now gets the correct bounds of thePositionIndicator
on screen. CurvedText/TimeText
- AddedModifier.scrollAway
, which scrolls an item vertically in/out of view, based on scroll state (with overloads to work withColumn
,LazyColumn
andScalingLazyColumn
).ScrollAway
is typically used to scroll aTimeText
out of view as the user starts to scroll a list of items upwards.CurvedText/TimeText
- Added support forfontFamily
,fontStyle
andfontSynthesis
inCurvedTextStyle
, usable oncurvedText
andbasicCurvedText
CurvedText/TimeText
- AddedfontWeight
to the constructor and copy method onCurvedTextStyle
ToggleControls
- Added animatedCheckbox
,Switch
andRadioButton
toggle controls for use withToggleChip
andSplitToggleChip
. These can be used instead of the static icons provided byToggleChipDefaults
(switchIcon
,checkboxIcon
andradioIcon
).- Placeholder - Added experimental placeholder support. This has three distinct visual effects designed to work together.
- Firstly a placeholder background brush effect used in containers such as Chip and Cards to draw over the normal background when waiting for content to load.
- Secondly a modifier (
Modifier.placeholder()
) to draw a stadium shaped placeholder widget over the top of content that is being loaded. - Thirdly a modifier gradient/shimmer effect (
Modifier.placeholderShimmer()
) that is drawn over the top of the other effects to indicate to users that we are waiting for data to load.- All of these effects are designed to be coordinated and shimmer and wipe-off in an orchestrated fashion.
- Core Compose dependencies updated from 1.2 to 1.3
API Changes
- Font parameters (
fontFamily
,fontWeight
,fontStyle
&fontSynthesis
) can now be specified directly as parameters ofcurvedText
(Idc422)
Bug Fixes
curveText
andbasicCurvedText
will now work properly with talkback (the have a properly sized and placed (but empty) compose-ui node associated with them, using the text as content description) (I7af7c, b/210721259)- Bug fix to the
Picker
whenPickerState.repeatedItems = false
to add an explicit setting of autoCentering params on the Pickers internalScalingLazyColumn
to ensure that it is possible to scroll the zero'th option to the center of the view. (I8a4d7)

's offset parameter to Dp for consistency withModifier.offset
(previously it was in pixels). Also, refactored as aLayoutModifier
for efficiency. (I9f94b) - As part of the new toggle controls API, we have renamed
RadioButton’s circleColor
toringColor
. (I28fa9) - We have added animated
Checkbox
,Switch

are released. Version 1.1.0-alpha05 contains these commits.
Bug Fixes
- Button roles were added to
InlineSlider
andStepper
so that Talkback can recognise them as buttons. (Icb46c, b/244260275) - We have corrected the z-order of position and page indicators in the Scaffold. The indicators will now sit on top of the vignette and so will not be obscured by the vignette if it is present. (Ib988f, b/244207528)
Version 1.1.0-alpha04
August 24, 2022
androidx.wear.compose:compose-foundation:1.1.0-alpha04
, androidx.wear.compose:compose-material:1.1.0-alpha04
, and androidx.wear.compose:compose-navigation:1.1.0-alpha04
are released. Version 1.1.0-alpha04 contains these commits.
API Changes
- We have updated a number of the default colors in the MaterialTheme in order to improve accessibility as the original colors did not have sufficient contrast resulting in difficulties for users to differentiate chip/card/button backgrounds from the theme background color. The updated colors are surface(0xFF202124->0xFF303133), onPrimary(0xFF202124->0xFF303133), onSecondary(0xFF202124->0xFF303133), primaryVariant(0xFF669DF6->0xFF8AB4F8) and onError(0xFF202124->0xFF000000). The changes in colors though relatively subtle may impact existing screenshot tests. (81ab09)
Bug Fixes
- Fix a logic bug in
ScalingLazyColumn
that could result in lists with a small (typically exactly 2) number of list items not completing initialization and as a result being transparent. (504347)
Version 1.1.0-alpha03
August 10, 2022
androidx.wear.compose:compose-foundation:1.1.0-alpha03
, androidx.wear.compose:compose-material:1.1.0-alpha03
, and androidx.wear.compose:compose-navigation:1.1.0-alpha03
are released. Version 1.1.0-alpha03 contains these commits.
New Features
- We have added a new outlined style for
Chips
andButtons
and newOutlinedChip
andOutlinedButton
composables that provide a transparentChip/Button
with a thin border. (Id5972)
API Changes
- Added overloads for modifying button shapes (Icccde)
Bug Fixes
- We have corrected the size of the toggle control area of the
ToggleChip
as it was not matching its UX spec. The UX Spec calls for a 4.dp spacer between the label and a 24x24.dp toggle control icon area giving a total 28.dp width. However the implementation is incorrectly giving 36x24.dp toggle control area. This results in taking away 8.dp of usable text label area. NOTE: This bug fix gives additional space for the text label and as result can (positively) impact the text layout for overflowing text. If you have screenshot tests includingToggleChips
they may need to be updated. (I514c8, b/240548670)

changes from a linear gradient of 75% surface to 32.5% primary to 0% surface to 50% primary. (I43bbd) - We have added a background color (
MaterialTheme.color.surface
) behindChip/ToggleChips
that have gradient backgrounds in order to ensure that they are properly visible in the unlikely event that a light color is used behind them. (Ibe1a4, b/235937657) - Picker items are now always center-aligned, fixing a bug when setting
gradientRatio
to zero had the side-effect of changing the alignment. (I712b8)

Bug Fixes
- We have corrected the direction of the gradient for Cards in right to left (RTL) mode. It was top left->bottom right, and it is now top right->bottom left. (Ic2e77)
- We have updated the default gradients for
Chip/ToggleChip/Card
to bring them in line with the latest UX spec.ChipDefaults.gradientBackgroundChipColors
has been updated to start from 50% of primary rather than 32.5%.CardDefaults.cardBackgroundPainter
has been updated to start from 30% of primary and end at 20% ofonSurfaceVariant
(was previously 20% to 10% onSurfaceVariant).ToggleChip.toggleChipColors
changes from a linear gradient of 75% surface to 32.5% primary to 0% surface to 50% primary. (I43bbd) - We have added a background color (
MaterialTheme.color.surface
) behindChip/ToggleChips
that have gradient backgrounds in order to ensure that they are properly visible in the unlikely event that a light color is used behind them. (Ibe1a4, b/235937657) - We have updated the baseline profile rules packaged with the Wear Compose library (I9c694)

, androidx.wear.compose:compose-material:1.0.0-rc01
, and androidx.wear.compose:compose-navigation:1.0.0-rc01
are released. Version 1.0.0-rc01 contains these commits.
API Changes
- Interfaces in compose libraries are now built using jdk8 default interface methods (I5bcf1)
Bug Fixes
- We have removed the explicit call to
fillMaxWidth()
on list header as it is not needed and can result in problems if aScalinglazyColumn
has a mixture ofListHeader()
andChip()
components as the width will tend to grow/shrink asListHeader
items are scrolled in/out of view. (I37144, b/235074035) - We have fixed a bug in the
ScalingLazyColumn
that could result in the list items not drawing correctly until scrolled if the 0th list item was large enough (including padding) (Ic6159, b/234328517) - We have made a small adjustment in the
ScalingLazyColumn
easing as items reach the edge of the screen to match UX spec updates. Old valuesCubicBezierEasing(0.25f, 0.00f, 0.75f, 1.00f)
-> new valuesCubicBezierEasing(0.3f, 0f, 0.7f, 1f)
. To keep the old behavior you can override thescalingParams
ofScalingLazyColumn
(Ie375c) - We have added padding to the
CompactChip
in order to ensure that its tap target size is at least 48.dp high to meet the Material accessibility guidelines. This might impact any layouts you have usingCompactChips
as they will be taking up additional space. (I3d57c)
Version 1.0.0-beta03

are released. Version 1.0.0-beta03 contains these commits.
New Features
- We have made
ScalingLazyColumn
work in Compose@Preview
mode. (I3b3b6, b/232947354)
API Changes
- We have changed the default value for the
ScalingLazyColumn.horizontalAlignment
property from Start toCenterHorizontally
to ensure that when list items do not fill the entire width of the column they will be aligned for maximum visibility. To switch back to the previous behavior sethorizontalAlignment = Alignment.Start
.(I9ed4b)
Known Issues
- CompactChip’s tap/touch height is smaller than Material accessibility guidelines. This will be corrected in the next release (15th June). If you are using CompactChip this will affect your layouts as CompactChips will now have additional padding above and below. Please adjust and test your layouts or see the bug comments for a workaround to use the existing behavior. (b/234332135)
Bug Fixes
- New demo to animate adding or removing a start text on a
TimeText
. (I16d75) - Add tests for
HorizontalPageIndicator.PagesState
(I64ed0) - Updating
TimeText
closer to UX specs (Ib7ea1)

, and androidx.wear.compose:compose-navigation:1.0.0-beta02
are released. Version 1.0.0-beta02 contains these commits.
New Features
- Picker now always responds to scroll events even when in read-only mode. This avoids the need for users to first select a Picker by tapping, before they can scroll. In read-only mode, options other than that currently selected are obscured by a shim in
gradientColor
. (I72925) - We have changed the UX behavior of
Chip/ToggleChip/CompactChip/SplitToggleChip
to stop them from doingfillMaxWidth
by default. Instead they will grow to fit their contents. To keep the previous behavior simply addmodifier = Modifier.fillMaxWidth()
(I60a2c, b/232206371)
Bug Fixes
CurvedTextStyle
constructor taking aTextStyle
now also respects thefontWeight
(This may be added to the constructor and copy methods in future revisions of the API) (Ieebb9)- Edge swiping improvements. When
Modifier.edgeSwipeToDismiss
is used and a swipe to the left is triggered from the edge area, it no longer triggers swipe-to-dismiss when swipe direction changes to the right. Previously, it was possible to trigger swipe-to-dismiss by swiping to the left and then swiping to the right.(I916ea) HorizontalPageIndicator
now shows up to 6 pages on the screen. If there are more than 6 pages in total, it shows a half-size indicator on the left or right, with a smooth transition between pages.(I2ac29)- Improved default snap behavior on
ScalingLazyColumn
andPicker
(I49539) - Edge swiping improvements. When
Modifier.edgeSwipeToDismiss
is used, swipe-to-dismiss only triggers when first touch lands on the edge and swiped to the right, Previously it was possible to trigger swipe-to-dismiss by swiping from any part of the screen if a scroll reaches the start.(I8ca2a)

What’s in Compose for Wear OS 1.0
The 1.0.0-beta01
of Compose for Wear OS marks an important milestone as the library is feature complete and the API locked.
Wear Compose Material components in the 1.0 release include:
- Material Theme - used as a replacement for the Compose for Mobile
MaterialTheme
, provides the colors, shapes and typography for building components on Wearables that implement the Wear Material Design UX guidelines out of the box. Button
,CompactButton
andToggleButton
- Button offers a single slot to take an icon, image or short text (3 characters max). Circular in shape with recommended sizes for default, large or small buttons.CompactButton
offers a single slot to take any content (icon, image or text) and is circular in shape with background size extra small.CompactButton
has optional transparent padding around the background that increases the clickable area.ToggleButton
is a button that offers a single slot to take any content (short text, icon or image) and has on/off (checked/unchecked) states with coloring and different icons to show whether checked or not- Cards - used to display information about applications such as notifications. Flexible design for different use cases with
AppCard
andTitleCard
giving different layouts and support for images as either card contents or backgrounds. - Chips - stadium shaped components similar to buttons, but with a larger area and multiple slots to allow for labels, secondary labels and icons. In different sizes and with support for images as backgrounds.
- ToggleChips and SplitToggleChips - a Chip with a checked/unchecked state and the addition of a
ToggleControl
slot to show an icon such as a switch or radio button to show the checked state of the component. In addition, theSplitToggleChip
has two tappable areas, one clickable and one toggleable. - CircularProgressIndicator - Wear Material progress indicator with two variations. The first expresses the proportion of completion of an ongoing task and supports a gap in the circular track between start and end angles. The second indicates indeterminate progress for an unspecified wait time.
- curvedText - forms part of the DSL for describing
CurvedLayouts
, along withcurvedRow
andcurvedColumn
, to lay out components around circular devices. See Wear Component Foundation below for more details onCurvedLayout
andCurvedModifier
(this plays a similar role to Modifiers in the non curved world and allows for configuration of various aspects of layout, padding, gradients, etc). - Dialog, Alert and Confirmation - Dialog displays a full-screen dialog, layered over any other content, and supports swipe-to-dismiss. It takes a single slot which is expected to be opinionated Wear Material dialog content such as Alert or Confirmation. Alert is opinionated dialog content with slots for icon, title and message. It has overloads for either two negative and positive buttons shown side-by-side or a slot for one or more vertically stacked chips. Confirmation is opinionated dialog content that displays a message for a given duration. It has a slot for an icon or image (that could be animated).
- HorizontalPageIndicator - shows horizontal page position in a fashion appropriate to the Wearable form factor. Designed to take the full screen and show a curved indicator on round devices. Can be used with the Accompanist page viewer.
- Icon - A Wear implementation of Icon which takes color and alpha from the Wear Material Theme. For a clickable icon, see Button or Chip.
- Picker - displays a scrollable list of items from which to pick. By default, items will be repeated ‘infinitely’ in both directions. Can be displayed in read-only mode to hide unselected options.
- PositionIndicator - shows scroll position or other positional indication in a fashion appropriate to the Wearable form factor. Designed to take the full screen and shows a curved indicator on round devices.
- Scaffold - implements the basic Wear Material Design visual layout structure. This component provides an API to put together several Wear Material components (such as
TimeText
,PositionIndicator
andVignette
) constructing the screen, ensuring proper layout strategy for them and collecting necessary data so these components will work together correctly. - ScalingLazyColumn - a scrolling scaling/fisheye list component that forms a key part of the Wear Material Design language. Provides scaling and transparency effects to the content items.
ScalingLazyColumn
is designed to be able to handle potentially large numbers of content items, which are only materialized and composed when needed. - Slider - allows users to make a selection from a range of values. The range of selections is shown as a bar, which can optionally be displayed with separators.
- Stepper - a full-screen component that allows users to make a selection from a range of values, using increase/decrease buttons at the top and bottom of the screen, with a slot in the middle for Text or a Chip.
- SwipeToDismissBox - handles the swipe-to-dismiss gesture. It takes a single slot for the background (only displayed during the swipe gesture) and the foreground content. Can optionally be combined with the androidx navigation library by using
SwipeDismissableNavHost
(see Wear Compose Navigation library below). - Text - A Wear implementation of the Compose Material Text component, taking color and alpha from the Wear Material Theme
- TimeText - a component for showing Time and application status at the top of the screen. Adjusts to screen shape by using curved text on round screens.
Vignette - a screen treatment for use in the Scaffold that blurs top and bottom of screen when scrollable content is in use.
The following components are also included from Wear Compose Foundation:
CurvedLayout - Wear Foundation
CurvedLayout
is a layout composable that places its children in an arc, rotating them as needed. This is similar to a Row layout curved into a segment of an annulus. Note that the content of aCurvedLayout
is not a composable lambda - rather, it is a DSL (domain-specific language). All elements in the CurvedLayout’s DSL support an optional modifier parameter, created fromCurvedModifier
.basicCurvedText - an element in the
CurvedLayout
DSL,basicCurvedText
allows developers to easily write curved text following the curvature of a circle (usually at the edge of a circular screen).basicCurvedText
can be only created within theCurvedLayout
to ensure the best experience, like being able to specify the positioning, and usingCurvedModifiers
. Note that in most cases curvedText should be used instead, since it uses Material theming.curvedComposable - wraps normal composable content so that it can be used with
CurvedLayout
. IfcurvedComposable
has several elements inside, they will be drawn on top of each other (like a Box). To put several composables along a curve, wrap each one withcurvedComposable
.curvedRow and curvedColumn - similar to Row and Column,
curvedRow
andcurvedColumn
can be nested inside aCurvedLayout
to lay elements out as needed. For acurvedRow
, the angular layout direction and radial alignment may be specified. For acurvedColumn
, the angular alignment and radial direction may be specified.CurvedModifier - all curved components accept a modifier parameter that can be created using
CurvedModifier
: background, size, weight and padding are supported.The following component is also included from Wear Compose Navigation:
SwipeDismissableNavHost - provides a place in the Compose hierarchy for self-contained navigation to occur, with backwards navigation provided by a swipe gesture. Content is displayed within a
SwipeToDismissBox
, showing the current navigation level. During a swipe-to-dismiss gesture, the previous navigation level (if any) is shown in the background.See previous release notes for the various Alpha releases for more details of what has been delivered.
API Changes
- Added
CurvedModifier.padding*
functions. These are used to specify additional space to be added around a curved component. (I4dbb4) - Removed
CompositionLocal
internal class (I42490) - We have added constant values for
Button
,CompactButton
andToggleButton
icon sizes, as guidance (I57cab) - Add enabled parameter to
AppCard
andTitleCard
. Now they have a similar API toandroidx.compose.material
Cards. When the parameter is set to false, the card will not be clickable. (Idc48d, b/228869805)
Bug Fixes
- Stepper now disables the decrease and increase buttons when the lower/upper limits have been reached (and applies ContentAlpha.disabled to the iconColor) (I4be9f)
- We have added 1dp padding around Picker contents when drawn with a gradient to prevent jitter on text seen when swiping. (I0b7b9)
- Add screenshot tests for
PositionIndicator
(I5e8bc) - Add more tests for
AppCard
andTitleCard
(I85391, b/228869805)
Version 1.0.0-alpha21
April 20, 2022
androidx.wear.compose:compose-foundation:1.0.0-alpha21
, androidx.wear.compose:compose-material:1.0.0-alpha21
, and androidx.wear.compose:compose-navigation:1.0.0-alpha21
are released. Version 1.0.0-alpha21 contains these commits.
New Features
- Added new curved modifiers to specify the background of a curved element:
CurvedModifier.background
,.radialGradientBackground
and.angularGradientBackground
(I8f392) - Allow curved text overflow mode (clip/ellipsis/visible) to be specified. (I8e7aa)
- Added
CurvedModifier.weight
modifier, similar to the one in Compose. This can be used on children of curvedRow and CurvedLayout (for width) and children of curvedColumn (for height). (I8abbd) - Added
CurvedModifier.size
,.angularSize
and.radialSize
modifiers to specify the size of a curved element. (I623c7)
API Changes
- Reorder parameters to ensure background is before color consistently across the Wear Compose API (I43208)
- Removed clockwise &
insideOut
parameters and replaced with more expressive constants on new classes. Curved layout direction can now beLayoutDirection
aware, and it is inherited when not specified (If0e6a) - We have replaced
autoCenter: Boolean
withautoCenter: AutoCentringParams
in order to fix an API issue with theScalingLazyColumn
. (Ia9c90) - We have renamed
iconTintColor
andtoggleControlTintColor
toiconColor
andtoggleControlColor
throughout the API (Chip/ToggleChip/Dialog/Slider/Stepper/...) as the color is applied to the icon/toggleControl slot. (Ied238) - Rewrite
PageIndicatorStyle
enum into value class (I2dc72) - We have added
RowScope/ColumnScope/BoxScope
to some of the slots in our Composables to indicate to developers what the layouts assumptions are. This will allow developers to use additional modifiers on some slot content and avoid the need to provide extra layout elements. Additionally we have made some minor updates to the AppCard/TitleCard colors so thattimeColor
andappColor
default tocontentColor
, these properties can still all be individually overridden if needed. (I26b59) - Made
SwipeToDismissBoxState.Companion
object private (I39e84) - Fix parameters order for
InlineSlider
andStepper
. A simple change to follow api guidelines (I11fec) - We have removed the Saver object for
SwipeToDismissBoxState
as it was not used. (Ifb54e) - We have updated
CompactChip
to bring it inline with the latest UX Specification. Padding has been reduced to horizontal = 12.dp and vertical = 0.dp. The font for label has been changed from button to caption1. The recommended icon sizes are 20x20 when both icon and label are present and 24x24 for an icon only compact chip. For the icon only use case we have also ensured that the icon is center aligned. (Iea2be) - We have added a number of new fields to
ScalingLazyListLayoutInfo
to enable developers to know the amount ofcontentPadding
andautoCenteringPadding
that has been applied. These can be useful for developers when calculating fling/scroll (I7577b) - We have implemented in/out transitions for Dialog. A
showDialog
parameter has been added and the Dialog now controls its own visibility (this enables Dialog to run the intro and outro animations when the Dialog is shown/hidden). Note that the outro animation is not performed when the user leaves the dialog via swipe-to-dismiss. We have also added a default value for state in the recently addedSwipeToDismissBox
overload. (I682a0) - In order to better support i18n and a11y we have changed
ToggleChip
andSplitToggleChip
so that they no longer have a default for thetoggleControl
slot. We have also changedToggleChipDefaults
so that the following methods now return ImageVector rather than Icon (note that as they no longer return @Composables they have changed to start with lower case),SwitchIcon()->switchIcon()
,CheckboxIcon->checkboxIcon()
andRadioIcon()->radioIcon()
- this allows and encourages developers to create their ownIcon()
composables with an appropriatecontentDescription
set. (I5bb5b) - We have added a
SwipeDismissableNavHostState
parameter toSwipeDismissableNavHost
. This supports use of edge-swiping on screens used as navigation destinations, becauseSwipeToDismissBoxState
can now be hoisted and used to initialize bothSwipeDismissableNavHostState
andModifier.edgeSwipeToDismiss
on screens that require edge-swiping. (I819f5, b/228336555)
Bug Fixes
- Ensure curved layouts are updated when needed. (Ie8bfa, b/229079150)
- Bug fix for https://issuetracker.google.com/issues/226648931 (Ia0a0a, b/226648931)
- Removed unnecessary experimental annotations (I88d7e)
Version 1.0.0-alpha20
April 6, 2022
androidx.wear.compose:compose-foundation:1.0.0-alpha20
, androidx.wear.compose:compose-material:1.0.0-alpha20
, and androidx.wear.compose:compose-navigation:1.0.0-alpha20
are released. Version 1.0.0-alpha20 contains these commits.
New Features
- Add
edgeSwipeToDismiss
modifier forSwipeToDismiss
. AllowsswipeToDismiss
to be active only on the left edge of the viewport. Used when the center of the screen needs to be able to handle horizontal paging, such as 2-d scrolling a Map or swiping horizontally between pages.(I3fcec, b/200699800)
API Changes
- Base implementation of
CurvedModifiers
, this opens the way to introduce ways to customize curved content (but noCurvedModifiers
are provided yet, and the ability to create custom modifiers may be available later) (I9b8df) EdgeSwipe
modifier documentation and default values update for better understanding .(I6d00d)- Add
PageIndicator
slot into Scaffold. By addingPageIndicator
directly into Scaffold we might assure that it will be correctly shown on circular devices. (Ia6042) - Remove default Icons from
InlineSlider
and Stepper parameters. This will help developers to be more attentive to localization and accessibility requirements. Usages of default icons were shown in demos and samples. (I7e6fd) - Replace Trailing and Leading parameter names with Start and End in TimeText (Iaac32)
- We have added a
SwipeToDismissBox
overload with anonDismissed
parameter to support the common usage of triggering a navigation event when the swipe gesture has completed. (I50353, b/226565726) - Removed
ExperimentalWearMaterialApi
annotations fromTimeText
usage (Ide520) - We have marked
ScalingLazyList/Column
scope and info interfaces as sealed as they are not intended for external developers to implement and this will allow us to add new members in them in future without binary breaking changes. (I7d99f) - We have added a new
flingBehaviour
property to the Picker and aPickerDefaults.flingBehaviour()
method to enable configuration of the fling behavior such as adding RSB support.PickerState
now implements theScrollableState
interface. (Ib89c7)
Bug Fixes
- Update the Android Runtime (ART) baseline profile rules for Wear Compose libraries. ART can leverage profile rules on devices in order to compile ahead-of-time a specific subset of the application to improve the performance of the application. Note that this will have no effect on debuggable applications. (Iaa8ef)
- Improve documentation (I2c051)
Version 1.0.0-alpha19
March 23, 2022
androidx.wear.compose:compose-foundation:1.0.0-alpha19
, androidx.wear.compose:compose-material:1.0.0-alpha19
, and androidx.wear.compose:compose-navigation:1.0.0-alpha19
are released. Version 1.0.0-alpha19 contains these commits.
API Changes
- Renamed
CurvedRow
toCurvedLayout
, and reworked to be a scope with a DSL. Using this DSL, more complex curved layouts can be specified using a series of nestedcurvedRow
andcurvedColumn
(Which are the curved layout equivalents of Row and Column). Inside these layout elements, three elements can be used:curvedComposable
(to add any @Composable),basicCurvedText
(foundation's curved text) andcurvedText
(wear material aware curved text). (Ib776a) - Make the side for the
PositionIndicator
configurable. The basic PositionIndicator’s position can now be configured to be End (layout direction-aware), OppositeRsb (takes into account screen rotation, to position itself opposite to the physical RSB), or the absolutes Left & Right. (I2f1f3) - For
SwipeToDismissBox
, we have renamedSwipeDismissTarget
.Original toSwipeToDismissValue.Default
andSwipeDismissTarget.Dismissal
toSwipeToDismissValue.Dismissed
. We have also movedSwipeToDismissBoxDefaults.BackgroundKey
andSwipeToDismissBoxDefaults.ContentKey
toSwipeToDismissKeys.Background
,SwipeToDismissKeys.Content
respectively. (I47a36) - We have added a read-only mode to Picker, for screens with multiple Pickers where only one Picker is editable at a time. When the Picker is read-only, it displays the currently selected option, and a label if one has been provided. (I879de)
SwipeToDismissBoxState
has been refactored to restrict the scope ofExperimentalWearMaterialApi
toModifier.swipeable
andSwipeableState
, which are now used internally.SwipeToDismissBoxState
now hascurrentValue
,targetValue
,isAnimationRunning
andsnapTo
members to support common use cases - please let us know if you require any further properties to be made available. Also fixed the behavior ofSwipeableState
in the case where the swipe offset is within a rounding error of an anchor. (I58302)
Bug Fixes
- Simplified and fixed code to detect if the content of a
ScalingLazyColumn
can be scrolled (used to decide if we display a scrollbar or not) (I7bce0) - Fixed a bug on Position Indicator when used with more than one state and switching between them (I320b5)
- We have updated the default Compose for Wear OS theme typography/fonts to match our latest UX guidance. Of note display1 (40.sp) and display2 (34.sp) are now smaller than their previous values and various other minor updates to line height and line spacing have been made. (Ie3077)
- We have added resistance to
SwipeToDismissBox
so that motion only happens when swiping to dismiss and not at all in the opposite direction. (Ifdfb9) - We have changed some of the default parameter values for the
CircularProgressIndicator
functions to bring them in-line with Wear Material Design UX guidance. For the Spinner/Indeterminant version the size (40->24.dp), indicatorColor (primary->onBackground), trackColor transparency (30%->10%) and stroke width (4->3dp) have been updated. For the Progress/Determinate version the trackColor transparency (30%->10%) has been updated. (I659cc) - We have updated the default scaling params of the
ScalingLazyColumn
in-line with the latest Wear Material Design UX specifications. Visually this results in list items starting to be scaled closer to the list center, but being less scaled at the list edge than before. (Ica8f3) - Some adjustments to
ScalingLazyColumnDefaults.snapFlingBehavior
to improve the end of the animation (If3260)
Version 1.0.0-alpha18
March 9, 2022
androidx.wear.compose:compose-foundation:1.0.0-alpha18
, androidx.wear.compose:compose-material:1.0.0-alpha18
, and androidx.wear.compose:compose-navigation:1.0.0-alpha18
are released. Version 1.0.0-alpha18 contains these commits.
API Changes
- Several improvements to PositionIndicator: ShowResult renamed PositionIndicatorVisibility. Some performance improvements to avoid recomputations when not needed (Iaed9d)
- The recommended coloring for the
SplitToggleChip
has been updated. SplitToggleChip's now have a solid colored background when checked or unchecked with the coloring of the ToggleControl being the primary indication of whether the component is checked or not. We have added a newToggleDefaults.splitToggleChipColors()
to support the new color scheme. We have also simplified thetoggleChipColors()
methods removing the splitBackgroundOverlayColor (I7e66e) - We have added unadjustedSize to the
ScalingLazyListItemInfo
as it is not safe to calculate the original item size using the scaled size and scaling factor due to float maths precision. (I54657, b/221079441) - Add
HorizontalPageIndicator
. It represents a total number of pages and a selected page. Might be linear or curved, depending on the shape of the device. It also supports custom indicator shape, which defines how each indicator is visually represented. (Iac898) - We have updated
PickerState
so that the numberOfOptions can be updated. This supports use-cases such as aDatePicker
, when the number of days in the month changes depending on the month selected. The constructor parameter for PickerState has changed to initialNumberOfOptions accordingly. (Iad066) - Hide the
PositionIndicator
when is a scrollbar and can't scroll. (Id0a7f) - For consistency with Scaffold, our full-screen Dialog component now displays a
PositionIndicator
and aVignette
. We are also now usingScalingLazyColumn
instead ofColumn
, which means that the Dialog contents are now inScalingLazyListScope
(and typically need to be enclosed by item { /* content */ }). Dialog supports the verticalArrangement parameter accordingly. (Idea13) - We have changed the name of
ToggleChip
andSplitToggleChip
toggleIcon property to toggleControl to better align with Material Design in order to help designers and developers navigate the API. (If5921, b/220129803) - We have added a new entry caption3 to the Wear Material Theme Typology.Caption3 is a small font used for the extra long-form writing like legal texts. (I74b13, b/220128356)
Bug Fixes
- Stop the snapping animation when we are there. (Idb69d)
- Animate changes in PositionIndicator. (I94cb9)
- Based on UI/UX feedback we have changed the
ScalingLazyColumn
autoCentering so that it will provide only enough space to make sure the items with indexScalingLazyListState.initialCenterItemIndex
or higher will be able to be fully scrolled to the center of the viewport. This allows developers to place one or two items about the item initially in the center which are not scrollable into the middle. This will mean that an autoCenter'ingScalingLazyColumn
will not be able to scroll above theinitialCenterItemIndex/initialCenterItemScrollOffset
(I22ee2) - We have added a demo for a Date Picker and fixed a bug in
PickerState
where the initiallySelectedOption was not applied until the Picker had been displayed. (Id0d7e) - In order to reduce the clipping of wider
ScalingLazyColumn
items on circular screens we have increased the default horizontal content padding from 8 to 10 dp. (I0d609) - Ensure the
PositionIndicator
is shown when scrolling. (Ied9a2)
Version 1.0.0-alpha17
February 23, 2022
androidx.wear.compose:compose-foundation:1.0.0-alpha17
, androidx.wear.compose:compose-material:1.0.0-alpha17
, and androidx.wear.compose:compose-navigation:1.0.0-alpha17
are released. Version 1.0.0-alpha17 contains these commits.
New Features
- We have added snap support that can be used with
ScalingLazyColumn
. SetflingBehavior = ScalingLazyColumnDefaults.flingWithSnapBehavior(state)
to enable snap support. (I068d3, b/217377069) - We have added demos for Picker used to select a time in either 24 hour or 12 hour clock. (Ie5552)
API Changes
- Fix an issue with
TimeText
custom fonts & styles on square device (Iea76e) ScalingLazyListLayoutInfo
now hasreverseLayout
,viewportSize
and orientation properties matching those fromLazyListLayoutInfo
(I4f258, b/217917020)ScalingLazyColumn
now has auserScrollEnabled
property matching that fromLazyList
(I164d0, b/217912513)- Pickers now have a gradient on the top and bottom by default (Iab92a)
Bug Fixes
- We have modified
ScalingLazyColumn
so that it no longer greedily fills all of the space in its parent. Instead it will take its size from the size of its contents. This makes it consistent with the behaviour ofLazyColumn
. If you want to reinstate the old behaviour then passModifier.fillMaxWidth()/width()/widthIn()
to theScalingLazyColumn
(I51bf8) - We have improved the exception message in
SwipeDismissableNavHost.kt
that was triggered if the navigation backstack was empty. (I1b1dc)
Version 1.0.0-alpha16

, androidx.wear.compose:compose-material:1.0.0-alpha16
, and androidx.wear.compose:compose-navigation:1.0.0-alpha16
are released. Version 1.0.0-alpha16 contains these commits.
New Features
- Add
CircularProgressIndicator
. Progress indicators display the length of a process or an unspecified wait time. Supports a gap (cutout) for TimeText or other components if used full-screen. (Iab8da)
API Changes
- Pickers now have a
flingBehavior
parameter, the default value makes them snap to the closest option when scrolling/flinging. (I09000) - Additional integer API for InlineSlider and Stepper (I1b5d6)
Bug Fixes
- We have changed the default initialCenterItemIndex for the
ScalingLazyListState
from 0->1. This means that unless overridden on state construction withScalingLazyListState.rememberScalingLazyListState(initialCenterItemIndex =
)
then the 2nd list item (index == 1) will be placed in the center of the viewport at initialization and the 1st (index == 0) item will be placed before it. This allows for a better default visual effect out of the box as most of the viewport will be filled with list items. (I0c623, b/217344252) - We have reduced the
ScalingLazyColumn
defaultextraPadding
that is provided to ensure that there are plenty of list items to draw (even when we are scaling some of them down in size) from 10% to 5%. This will avoid composing extra list items that might not appear in the viewport. If non standard scalingParams are being used (more extreme scaling for instance) the developer can adjust extra padding usingviewportVerticalOffsetResolver
. (I76be4) - Fix an issue with TimeText on multiple lines on square device (Ibd3fb)
- We have modified
ScalingLazyColumn
so that it no longer greedily fills all of the space in its parent. Instead it will take its size from the size of its contents. This makes it consistent with the behavior ofLazyColumn
. If you want to reinstate the old behavior then passModifier.fillMaxSize()
to theScalingLazyColumn
- NOTE: This change is incomplete and will be addressed in a follow up change in the next Alpha release. (I3cbfa)
Version 1.0.0-alpha15

, androidx.wear.compose:compose-material:1.0.0-alpha15
, and androidx.wear.compose:compose-navigation:1.0.0-alpha15
are released. Version 1.0.0-alpha15 contains these commits.
API Changes
- We have added a new property
autoCentering
to theScalingLazyColumn
. When true (the default) this will ensure that all items including the first and last can be scrolled so that they are visible in the center of the lists viewport. Note that if using auto-centering you will probably want to set vertical content padding to 0.dp. If both autoCentering and vertical content padding are provided then they will both result in additional space being available before the first and after the last list items allowing them to be scrolled even further. (I2a282, b/214922490) - We have added a
Dialog
component that enables any composable to trigger a full screen dialog that sits on top of other content. When shown, the dialog supports swipe-to-dismiss and will show its parent's content in the background during the swipe gesture. The dialog content is expected to beAlert
orConfirmation
(renamed from earlier componentsAlertDialog
andConfirmationDialog
) -Alert
,Confirmation
andDialog
are all in theandroidx.wear.compose.material.dialog
package. Alert and Confirmation can be used as navigation destinations. Also, added ColumnScope to Alert and Confirmation parameters as necessary. (Ia9014) - We have removed
onSurfaceVariant2
from the Compose for WearOS Material Theme Colors and replaced uses in the library withonSurfaceVariant
. (Icd592) - Added a method to programmatically select an option on the
PickerState
, the initially selected option can now also be specified when creating aPickerState
. (I92bdf) - We have added support for customizing the fling behavior of the
ScalingLazyColumn
. (I1ad2e, b/208842968) - We have added
NavController.currentBackStackEntryAsState()
to theWear.Compose.Navigation
library. (If9028, b/212739653) - Added
Modifier.onRotaryScrollEvent()
andModifier.onPreRotaryScrollEvent()
for Wear devices with a rotating side button.(I18bf5, b/210748686)
Version 1.0.0-alpha14
January 12, 2022

, androidx.wear.compose:compose-material:1.0.0-alpha14
, and androidx.wear.compose:compose-navigation:1.0.0-alpha14
are released. Version 1.0.0-alpha14 contains these commits.
New Features
We have added a number of methods to
ScalingLazyListState
to allow developer control over scrolling to specific list items and also setting the initial list item and offset.As part of this change we have also modified the ScalingLazyList so that it is oriented around the center of the viewport of the ScalingLazyList rather than the start of the viewport.
A new property
anchorType: ScalingLazyListAnchorType = ScalingLazyListAnchorType.ItemCenter
has been added to theScalingLazyList
to control whether the center (ScalingLazyListAnchorType.ItemCenter
) orEdge
(ScalingLazyListAnchorType.ItemStart
) should be aligned to the viewport's centerline.As a result the
ScalingLazyListItemInfo.offset
andScalingLazyListItemInfo.adjustedOffset
have changed and will now reflect the offset of the item with respect to both the position of the list item and theanchorType
of the list. E.g. for aScalingLazyColumn
withanchorType
ofItemCenter
and an list item positioned with its center on the centerline of the viewport the offset would be0
.The new methods are
scrollTo
,animatedScrollTo
,centerItemIndex
, andcenterItemOffset
. (I61b61)We have added a back button handler to
SwipeDismissableNavHost
, so that pressing back navigates to the previous level in the navigation hierarchy. (I5b086, b/210205624)

are released. Version 1.0.0-alpha13 contains these commits.
API Changes
- We have made
RangeIcons
internal (referenced internally byInlineSlider
andStepper
). (I927ec)
Bug Fixes
Fixed an issue where
SwipeDismissableNavHost
would add a destination to the Compose hierarchy before it has reached theCREATED
Lifecycle state, resulting in anIllegalStateException
. This fix was a prerequisite to updating dependency onnavigation-compose
to2.4.0-beta02
and beyond. (I40a2b, b/207328687)Added a Drawables enum class for getting drawable resources within the Wear Compose library, so that reflection is no longer needed. This fixes a bug where library drawables were removed when
minifyEnabled=true
orshrinkResources=true
). (Ib2a98)Added tests for
Stepper
in Wear Compose (I2d03a)Added samples for
SwipeDismissableNavHost
in Wear Compose Navigation. (I85f06)

, and androidx.wear.compose:compose-navigation:1.0.0-alpha12
are released. Version 1.0.0-alpha12 contains these commits.
New Features
We have added a Stepper component which allows users to make a selection from a range of values. Stepper is a full-screen control with increase and decrease buttons at the top and bottom, and a slot in the middle (expected to take either a Chip or Text). The button icons can be customized if required. (I625fe)
We have added 2 new composables for displaying dialogs: AlertDialog waits for a response from the user and displays a title, icon, message and either a) two buttons for simple positive/negative choices or b) vertically stacked chips or toggle chips for more flexible choices, ConfirmationDialog displays an acknowledgement with a timeout. This simple dialog has slots for a title and an (animated) icon. (Ic2cf8)
API Changes
- Add units (millis) to suggested dialog duration values. (I09b48)

, and androidx.wear.compose:compose-navigation:1.0.0-alpha11
are released. Version 1.0.0-alpha11 contains these commits.
New Features
- We have added a picker component that lets the user select an item from a scrolling list. By default, the list of selectable items is repeated 'infinitely' in both directions, to give the impression of a rotating cylinder seen from the side. Two features will be added in later releases: snapping to a value after a swipe/fling; adding a function to PickerState to set/scroll to the current value. (I6461b)
API Changes
- Added a ScalingLazyItemScope and some new modifiers fillParentMaxSize/fillParentMaxWidth/fillParentMaxHeight to allow list items to be sized based on the size of the parent container. Items can be set to fill all or a fraction of the parent’s size. This exposes functionality already available in the LazyRow/Column (I4612f)
- Added support to ScalingLazyColumn to allow items to have a key. Also added convenience methods to allow adding of items from Arrays and Lists. (Ic1f89)
Bug Fixes
- Additional examples for TimeText (I8cb64)

New Features
- Added a CurvedText component in material, a component allowing developers to easily write curved text following the curvature of a circle (usually at the edge of a circular screen). (I19593)
API Changes
- Added tests for TimeText (Idfead)
- Transform ArcPaddingValues into an interface. (Iecd4c)
- Added animation to SwipeToDismissBox (I9ad1b)
- Added hasBackground parameter to the SwipeToDismissBox API so that the swipe gesture can be disabled when there is no background content to display. (I313d8)
rememberNavController()
now takes a optional set ofNavigator
instances that will be added to the returnedNavController
to better support optional Navigators such as those from Accompanist Navigation Material. (I4619e)- Reference NamedNavArgument from navigation-common and remove copy from wear.compose.navigation. (I43af6)
Bug Fixes
- Fixed CurvedRow test flakiness on smaller devices. (If7941)
- Fixed possible flickering on CurvedRow when the content updates, and ensures the curved row is remeasured (Ie4e06)
- ChipDefaults.gradientBackgroundChipColors() has been updated in line with UX Spec changes. The gradient now starts with MaterialTheme.colors.primary with alpha 32.5% and ends with MaterialTheme.colors.surface with alpha @ 0% over a background of MaterialTheme.colors.surface @ 75% alpha. (Id1548)
- We have updated the colors for ToggleChips when in the selected state to match the latest Wear Material Design UX Spec guidance. When selected ToggleChips now have a gradient background from MaterialTheme.color.surface @ 0% alpha, top left, to MaterialTheme.color.primary @ 32% alpha, bottom right, over a background of MaterialTheme.color.surface @ 75% alpha. This results in a more subtle difference between checked and unchecked for the ToggleChip. (Idd40b)

, and androidx.wear.compose:compose-navigation:1.0.0-alpha06
are released. Version 1.0.0-alpha06 contains these commits.
New Features
- We have added Scaffold a top level application composable that provides a structure for handling PositionIndicators (like Scroll or Volume) position, an area at the top of the screen for displaying the time and application status, and also supports a Vignette to blur the screen top and bottom edge for scrollable content. The main area of the Scaffold is where the application contents are placed. (I5e0bf)
- Added TimeText implementation for Wear Compose (I5654c)
Wear Compose Navigation Library
We have added the first release of the Wear Compose Navigation library, which provides integration between the Wear Compose and Androidx Navigation libraries. It provides a simple means to navigate between @Composable functions as the destinations in your application.
This initial release provides:
- A
SwipeDismissableNavHost
composable that hosts a navigation graph and provides backwards navigation via swipe gestures NavGraphBuilder.composable
extension to assist with constructing navigation graphsrememberSwipeDismissableNavController()
to allow hoisting state
- A
Example usage where we create two screens and navigate between them:
val navController = rememberSwipeDismissableNavController() SwipeDismissableNavHost( navController = navController, startDestination = "start" ) { composable("start") { Column( horizontalAlignment = Alignment.CenterHorizontally, verticalArrangement = Arrangement.Center, modifier = Modifier.fillMaxSize(), ) { Button(onClick = { navController.navigate("next") }) { Text("Go") } } } composable("next") { Column( horizontalAlignment = Alignment.CenterHorizontally, verticalArrangement = Arrangement.Center, modifier = Modifier.fillMaxSize(), ) { Text("Swipe to go back") } } }
Wear Compose Navigation is packaged as a separate library so that simple WearCompose applications that implement their own hand-rolled navigation are not required to depend on the Androidx Navigation library.
API Changes
- Updated
SwipeDismissableNavHost
to supportrememberSaveable
by setting the key identity for background and content (I746fd) - We have added a PositionIndicator adapter that can handle LazyListState (I21b88)
- Updated SwipeToDismissBox to support rememberSaveable (Ie728b)
- We have added reverseLayout support to the ScalingLazyColumn. This allows for the reversing of the direction of scrolling and layout (I9e2fc)
- Deprecated
performGesture
andGestureScope
, which have been replaced byperformTouchInput
andTouchInjectionScope
. (Ia5f3f, b/190493367) - We have renamed VignetteValue to VignettePosition and renamed VignetteValue.Both renamed to VignettePosition.TopAndBottom. (I57ad7)
- We have renamed ScalingLazyColumnState to ScalingLazyListState, ScalingLazyColumnItemInfo to ScalingLazyListItemInfo, ScalingLazyColumnLayoutInfo to ScalingLazyListLayoutInfo and ScalingLazyColumnScope to ScalingLazyListScope in case we decide to add a ScalingLazyRow implementation in the future. (I22734)
Bug Fixes
- Updated CompactChip documentation to describe what happens if neither an icon nor a label is provided. (I4ba88)
- We have made some adjustments to the Wear card components. (I6b3d0)
- TitleCard spacing between Title and Body reduced from 8.dp to 2.dp.
- TitleCard header font changed from body to title3.
- Card background gradient changed to make the background appear darker.

are released. Version 1.0.0-alpha04 contains these commits.
New Features
- Added a SwipeToDismissBox and swipeable modifier that can be used to support a left-to-right swipe-to-dismiss gesture. Although independent of navigation components, this is expected to be used to exit one screen and navigate to another. Added integration tests to demo swipe-to-dismiss. (I7bbaa)
- We have added ScalingLazyColumnItemInfo and ScalingLazyColumnLayoutInfo interfaces to ScalingLazyColumnState class to enable developers to know the actual positions and sizes of items in the ScalingLazyColumn after scaling has been applied. We have also fixed a bug with the way that scaling was calculated when 'top' content padding is applied to the ScalingLazyColumn. (I27c07)
API Changes
- Add CurvedTextStyle class to specify curved text styling Options. Similar to TextStyle, but now only supports color, fontSize and background. More styling options will be added in the future. (I96ac3)
- We have added ScalingLazyColumnItemInfo and ScalingLazyColumnLayoutInfo interfaces to ScalingLazyColumnState class to enable developers to know the actual positions and sizes of items in the ScalingLazyColumn after scaling has been applied. We have also fixed a bug with the way that scaling was calculated when 'top' content padding is applied to the ScalingLazyColumn. (I27c07)
- Added
@ExperimentalWearMaterialApi

to make it clear that the background image with have a scrim drawn over it. (I53206) - Adding ScalingLazyColumn component that provides a list component for Wear Material that gives a fisheye view with the list contents scaling down in size and becoming transparent as they scale towards the edge of the component. (I7070c)
Bug Fixes
- We changed the default color of the appName content in AppCard in response to a UX Spec update. The default color for the appName is now
MaterialTheme.colors.onSurfaceVariant
. Additionally added a missing parameter doc description for the title slot. (Ic4ad1)

Bug Fixes
- Add tests for CurvedRow (I93cdb)
- Tying Wear Compose dependencies to Compose 1.0.0-rc01. (Ie6bc9)

androidx.wear.compose:compose-foundation:1.0.0-alpha01
and androidx.wear.compose:compose-material:1.0.0-alpha01
are released. Version 1.0.0-alpha01 contains these commits.
New Features
Wear Compose is a Kotlin, Compose-based library that supports Wear Material design, an extension of Material Design for WearOS wearables. This first alpha release contains early, functional implementations of the following:
- Material theme - configures the colors, typography and shapes consistently across the components used from this library.
- Chip, CompactChip - chips are stadium shaped and variations are available to take icon, label and secondary label content.
- - ToggleChip, SplitToggleChip - a specialized type of chip that includes a slot for a bi-state toggle icon such as a radio button or checkbox. In addition, the SplitToggleChip has two tappable areas, one clickable and one toggleable.
- Button, CompactButton - buttons are circular in shape, with a single content slot for an icon or minimal text (maximum 3 characters).
- ToggleButton - a button that turns an action on or off, with a single slot for icon or minimal text (maximum 3 characters).
- Card, AppCard - rectangular shaped with rounded corners, offering slots for content such as app icon, time, title and body.
Future releases will extend the Widget set adding support for Wear Material Design pickers, sliders, lists, page indicators, dialogs, scroll rsb indicators, toasts and more.
Additionally support will be provided for other Wearable Specific features such as curved layouts and text, as well as scaffolding to make it easy for developers to build Wearable apps/overlays.
Wear Compose Material is designed with the same principles as Compose Material, although being targeted at wearables. The Wear Compose Material library should be used in place of the Compose Material library when building for a Wearable device.
The two “Material” libraries should be considered mutually exclusive and should not be mixed in the same app. If developers find themselves including the Compose Material library in their dependencies it would suggest that either a) there are components missing from the Wear Compose Material library, please let us know what you need, or b) are using a component that we do not recommend for use on a Wearable Device.
